Circle

This mathematics video lecture is about another most important topic IIT-JEE mains maths examinations. In this maths video, we will understand “circles” under the topic coordinate geometry. This must be a familiar topic to all the JEE aspirants.

However, you will be able to know something new in this video. IIT-JEE maths examinations are a level higher than what you have studied earlier. Let us understand higher level concepts as per your IIT-JEE maths examinations.

Circle is a curve which has a center. Also, the distance to a moving point from that center is always constant. This distance is known as “r”. Hence, “c” is the center, the moving point is denoted by “p” = (x,y) and “r” is the radius. Now, this is the basic definition that we all must be aware of.

However, this concept is much broader when we take circumference under consideration. While finding the equation, center of the circle is not of much help. In fact, the equation of the circle should satisfy all the points lying on the circumference of circle. Circumference is the region surrounding the center of the circle.

In this iit jee mains maths video lecture we explain the basic to the students. After that we take them a level higher than the basics. Our motive is to make understand the entire concept to the IIT-JEE aspirants.

The general form of equation is denoted by ax 2+ 2hxy+ by 2 + 2gx + 2fy + c = 0. This is the general two degree equation form.

This also represents the equation of the circle x 2 + y 2 + 2gx + 2fy + c = 0, where a=1 & b=1 and h=0. Also, the delta here is not equal to 0 in this case.

Also, we will understand about the circle at origin in this video lecture for jee maths. The equation for the circle at origin is denoted by (x – h) 2 + (y – k) 2 = a2.

Now, while studying for this chapter, formula/ equations is the integral part of learning. Through these lectures we intent to impart theoretical and practical knowledge. In order to give a thorough learning you need to concentrate in the entire video on all the important formulas mentioned.

IIT-JEE mains maths exams are framed to give you a thorough knowledge of the syllabus. Our best efforts is to give you in-depth understanding of the topic through these video lectures of jee mains maths.
